The Sound of Pursuit

The Pebble in His Shoe

Hal Humphreys

Mike Spencer is a former journalist, a Bay-Area private investigator, and the author of Private Eye Confidential: Stories from a Real P.I. He's been a guest on our podcast several times and is a longtime contributor to Pursuit.

In this episode, Mike talks about an unsolved murder that's connected to a case he worked in 1998. It's the "pebble in your shoe," he says — a story of justice left undone, and he cannot let it go. Over the past several years, he's been telling the story of that killing and his investigation in a podcast, "The Gary Murphy Assassination: A San Francisco Cold Case." He adds new episodes as he gets closer to the real story of that murder. 

Join Hal and Mike as they talk about chasing the truth, no matter how long it takes.
